This "invention relates to railway- Ytrain refrigerator Sandbox "cars, and has for its object to provide' a construction wherein the side wall is ventilated to reduce the amount oi moisture permitted rtocome in contact with the insulation of arefrigerator car wallor the side wall 'of a boX'car,' and furthermore to provide a metallic sheathing on the'outside. of the wall of the car and^ spaced apartv therefrom to provide an air chamber, which chamber is'provided withopenings near th-etop and bottom thereof. respectively, so asto permit circulation of air between the wall of .the car and the sheathingwhich would prevent hot :airfrom being retained against thefcar wallan'd so attach the metallic sheathingto' the "frame members of the car thatiit can be readily removed' (andy replaced) to facilitate the removing', replacing andkrepairing of the insulation of the `car wallr'or the car wall invention. f

Y Another Objectis to attach such a removable sheathing to the cark atitsupper margin (or lower margin ifdesired) soas to permit relative vertical movement therebetween and sov as to prevent any substantial horizontal movement between these elements]l whereby the Weaving` and torsional movements of the car,

in' service 4do lnot transmit buckling stresses upon the sheathing thereby allowing thinnermaterialto be used for the sheathing plates.

l`Another object oftheinventionis to fso attach the removable sheathing to the upper plate member of thecar so that the plate may act as a hoodor shield-'for lthe Ventilating ing spaced apart froml eachother to'form an airv chamber therebetween and toprovi'de Lven-.iy tilating' means'for the'air chamber'adjacent the upper and lower Jframe' members respectively of the carfand to so arrange thev attach-t? ments of the .sheathing to the upper and lowerl frame members respectively that the ventilating apertures are shielded or protected from the direct entrance of rain, snow or'other forms of moisture therethrough-- f VIn the drawings:

, y 70 f In the form illustrated in Figs.l 1--tog4in 'clusive'thevinsulating ywall of the-Carcom- 'l roofV insulation and 12 isv part of. the. floor` insulation. The rolled steel upper 'side' plate 13 and the rolled steellowerside sill 14 form Y the -oppositely disposed longitudinal side rame'membersoi the car which are connectedk v members or postsand braces to form atruss. These verticalfand diagonal members are not shown except as 15 and 16 in Figs.i k3 and 4.

' It is customary to nail-vertical sheathing 00- die the sheathing pla-te 20 and the depending boards over the outside of the insulating wall but the weaving and other movements of the carin motion loosen the nails,cracl{ the boards and separate them so that they leal; and permit moisture to come in contact with the insulating material, which material acts like a sponge and readily absorbs it and transfers the moisture to the adjacent insulating layers. The increased weight of the insulation caused by the moisture content causes it to break away from 'its moorings and it is jarred to the lower'part of the car, thus,of course, at least partially depriving the car of its insulation. Even though the insulatingcmaterial is not displaced its insulating capacity is materially reduced yb'ybecoin'ing moist'.l

My invention is an improvement` ony such construction as I eliminate the wooden'sheath-` ing and substitute there-for a--metallicsheathing 20 which cannot be cracked or split or otherwise' damaged sok as `to permit the 4water to comein'contact with the insulation'. Furthermore, I provide an air chamber 212 be-` tween thev insulation 8 and metallic sheath: ingf20 and alsoprovidemeans of Ventilating this air-chamber, thus preventing any condensation on-` the inside ofthe metallic plate from wetting.theinsulation.

It is understood, of course, in my invention that moistair (and perhaps driven snow) would andwill come inY contact withthe insulating material and therefore it will beVI come necessary to remove and replace -the'insulation, therefore, at' spacedV intervals, I provide angle clips (22) which are'rigidly securedto the side plate of the car as at (23) f but which are detachably secured byv bolts 24 to the inetallic sheathing 20. At'theA lower partjof the end wall, at spaced intervals,

Ifprovide clips'25 which are rigidly securedv to the side sill as at (26) but which are bolted' asat (27through the medium off-a, continuous connecting angle 28 to the metallic sheathing, 20. y

The side plate'is Lprovided with a depend ing flange 32 which is spaced awayfromthe metallic vsheathing. 20 'and which overlapsa andoverhangsthe metallic sheathing and the Ventilating apertures between ad-jacent;

clips 22. (Of course, the apertures may actually be in the side sheathing but thisis immaterial as far as lthis invention is concerned.) The lsheathing 20 overhangs the side sills and the Ventilating apertures3l'adjacent"thereto to'prevent rain or moisture frombeating directly' into the air chamber.

Fig. 2-shows a modified constructionwhere inthe sheathing/.20 is provided with integral rigidifying corrugations orv embossments 33 which preferably terminate" adjacent the posts 1G, as shown in Fig. 4. A stifl'ening flange 34fis provided adjacent the top'of'the plate 2O 'and ventilationis provided between flange 32 of the side plate without perforating any of the members.

Fig. 4 shows a readily detachable means of securing the plates 20 to the vertical post 16 wherein a stud rivet 36 secures a continuous strip 37 to the post which frictionally secures the vertical edges of the adjacent plates in place.

Figs. 5 and 6 show a modified form of the invention applied to a boX car wherein the retaining wall 40 comprises a plurality of preferably horizontal boards spanning the distance between the 'upper frame member or sideplate 41 and the lower frame member or side sill 42. The floor 43 rests upon the side sill42. 'Ihe frame'members, such as corner post, door post, intermediate vertical post and Ldiagonal braces, overlap and are secured to thesilland pla-te.` The removable sheathing 45 is spaced apart from the retaining wall 40 preferably an amount equal to the width 'of the posts.V Nailingfstrips 46 for-the retain-` ing wall maybe bolted to these posts.'`

The lower margin ofthe sheathingis attached by a connecting angle47 to the-*spaced apa-rt clips 48. The upper margin ofthe sheathing is formed witha flange 49 to form ar horizontal portion which isiprovided with anaperture 50. The angular memberl; is` secured tothe side plate and isv provided with val depending; piece or' tongue 52 which protrudes through and` loosely engages-i thev apertureqO. The ,tongue and aperture maybe` roundk but are preferablywelongated, as

shownin Fig. 6, to .minimize the friction and The aperture isA preferably burred (53)l to -increase the-bear?

at the same" time, retains the-sheathing; in a substantially vertical position byl preventing any substantial horizontal movement between the sheathingandthesideplate. The lower-` marginof the sheathing is preferably rigidly and removably attached to the side sill. If preferred thel loose Vconnection may be 'posi-v tioned atthe bottom of the sheathing and theV rigid'connection at the top Vofthe, shea-th-4 ing:

The side plate is'preferably provided with av iiange 55which overhangs and overlaps the YVentilating apertures. Y

The accompanying drawings Iillustrate the preferred'` form of the invention,though 'itis f* to be -understood thatthein-ventionlis not limited to the exact details of construction shown? f and described, as it is obvious that various modiiications thereof within the scope of the claims will occur to persons skilled in the art.
